Study debunks ignorant misconception on breast cancer

Mickey passed this item along from Yahoo News (Breast cancer genes can come from father)

A deadly gene’s path can hide in a family tree when a woman has few aunts  and older sisters, making it appear that her breast cancer struck out of  nowhere when it really came from Dad.

Half of genetic breast cancers are inherited from a woman’s father, not  her mother. But unless Dad has female relatives with breast cancer, the faulty  gene may have been passed down silently, without causing cancer. (Men can get  genetic breast cancer, too, but it’s not common.)

Weitzel said doctors often overlook the genetic risk from the father’s side  of the family.

The large majority of genes are on the 22 pairs of chromosomes that one gets equally from both parents.  Although breast cancer is expressed almost exclusively in females, it always surprised me when people assumed it was only passed from female to female.  No known mechanism of inheritance has such a transmission pattern.

  1. Didn’t think a health business blog would be very interesting, but I was wrong. I’ve read several of your posts including this one and all were very well done. I did not know men could get breast cancer. Makes sense, but you just never hear about it.

    I’m adding you to my blogroll. Hope you approve the heading I’m giving you.

  2. How would you like to make a difference in breast cancer research? The Sister Study needs your help to determine if breast cancer is caused by something women come in contact with at work, at home, in their communities or in the personal products they use.

    The Sister Study is looking for 50,000 women to help discover the environmental and genetic causes of the disease. Women ages 35 to 74 are eligible to join if their sister (living or deceased), related to them by blood, had breast cancer; they have never had breast cancer themselves; and they live in the United States or Puerto Rico.

    ENROLL TODAY or simply help spread the word to women in your community! Either way, you can help find the causes of breast cancer!!
